About YEAST FERMENT EXTRACT
A fermented yeast extract (think SK-II's secret ingredient) — loaded with vitamins, amino acids, and minerals that nourish skin and boost cell renewal. Well-tolerated by most skin types.
Detailed Analysis
Yeast Ferment Extract is obtained from the fermentation of Saccharomyces cerevisiae (baker's/brewer's yeast). Rich in B vitamins, amino acids, minerals, peptides, and organic acids, it functions as a skin conditioning agent. The fermentation process produces bioactive metabolites including galactomyces ferment filtrate (Pitera) analogues. Studies suggest it enhances cellular metabolism, promotes wound healing, and provides antioxidant protection. Widely used in premium K-beauty and J-beauty products. CosIng-listed with no GHS hazards. The ozone-layer restriction is a generic regulatory tag.
